Fence Repairs in Great Cornard - Looking After Your Fence Once It Is Fixed

The Repair Is Not the End of the Job

Once a fence has been repaired - posts reset, panels replaced, gravel boards renewed - the temptation is to forget about it until something goes wrong again. A better approach takes about an hour a year and can add years to the life of the whole run. This page covers what to do after a repair, how to spot problems early, and what simple maintenance actually makes a difference.

The advice below applies equally whether a professional carried out your repair or you are maintaining an existing fence.

What to Do in the First Few Weeks After a Repair

If posts have been set in concrete, avoid leaning anything against the new section for at least 48-72 hours while the concrete cures properly. New timber will look a different colour to the existing fence - this is normal. Pressure-treated timber has a green or brown tint that weathers to a more uniform grey over the first season. There is no need to apply anything to freshly tanalised timber immediately; the treatment needs time to settle into the wood first.

After two to three months, once the timber has dried and settled, is the right time to apply a preservative stain or fence treatment if you want one. Applying it too early, while the wood still carries moisture from the treatment process, reduces how well it bonds.

The One Habit That Prevents Most Fence Failures

The single most effective maintenance habit is keeping the base of the fence clear. Soil, compost, bark chippings or turf built up against the base of timber posts or panels traps moisture against the wood and accelerates rot. A post in dry, free-draining ground can last twenty years or more. The same post with soil piled against it at ground level may begin to rot within five to seven years.

Rake back anything that has accumulated against the fence base twice a year - once in spring and once in autumn. If you use raised beds or borders along the fence line, leave a gap of at least 50-75mm between the soil level and the base of the panels. Gravel boards exist precisely to take the ground contact away from the panels; keeping them clear lets them do that job.

Annual Check: What to Look For

A quick walk along the fence once a year - ideally after the autumn and before the winter storm season - catches problems while they are still minor. Look for these specific things:

• Posts that have developed any movement at the base. Push each post firmly at the top. No movement is good. Any rocking means the concrete is failing or the post is rotting below ground.
• Gravel boards that have gone soft, split or lifted away from the base of the panels. A damaged gravel board lets moisture into the bottom of the panels.
• Individual feather-edge boards that have split, cupped or pulled away from the arris rail. A single loose board lets wind get behind the panel and can lift the whole bay in a storm.
• Arris rails (the horizontal timber rails that boards are fixed to in close-board fencing) that have sagged, cracked or pulled out of their mortise holes in the posts. A failing arris rail is an early warning that a section is about to come down.
• Panel frames on lapped panels that have started to delaminate or swell at the corners. Once the corners open up, water gets inside the layers and the panel deteriorates quickly.
• Gate posts that have moved. Gate posts carry dynamic load every time the gate swings, and they often move before adjacent fence posts do.

Treating Timber: What Actually Helps

Fence treatment or preservative stain applied to dry, weathered timber does extend the surface life of panels and boards. The best products to use are oil-based or spirit-based preservatives rather than water-based paint, which sits on the surface rather than penetrating the grain. Apply with a brush rather than a roller to get the product into the grain properly, and pay particular attention to end grain on boards - end grain absorbs moisture far faster than the face of the board.

A common mistake is treating only the garden-facing side of a panel. Both sides benefit, and the back face - particularly on close-board fencing where arris rails are fixed - is often the side that deteriorates first because it is less exposed to sunlight and stays damp longer. If access allows, treat both faces.

Retreating roughly every two to three years is enough for most timber panel fencing. You do not need to strip the old treatment before applying new product unless the surface has peeled badly.

Vegetation Growing Against the Fence

Climbers, ivy and hedging against a fence significantly reduce its lifespan. Ivy in particular forces its way into any gap and holds moisture against the timber. If you want to grow climbers against the fence, use trellis fixed to battens that hold it 50mm away from the fence face, rather than attaching growth directly to the panels or posts. This allows air to circulate and the fence to dry out between wet periods.

Overgrown hedging that leans into the fence applies sustained pressure over time. Branches that rest against panels in wind act as levers and work panel fixings loose. Keep vegetation trimmed back from the fence face where possible.

After a Storm: What to Check

After any period of strong wind, walk the fence line before the next heavy rain. Panels that have lifted slightly but not blown down will let a significant amount of water in through any gap at the top or sides. Check that all panel tops are sitting level and that no boards have pulled away from the arris rails. If a post has moved noticeably, do not attempt to brace it yourself with timber props - a post that has shifted needs to be assessed and re-set correctly rather than held temporarily in position.

When to Call for a Repair Rather Than Wait

A small problem addressed promptly is almost always cheaper than the same problem six months later. Specific situations that warrant a call rather than a wait:

• A gravel board that has split or rotted through - it will let moisture into the panel base immediately
• An arris rail that has pulled out of the post - the boards it supports will begin to fall within weeks
• A post with visible rot at ground level - it will not recover and will fail at the worst possible time
• A gate post that is leaning noticeably - the hinge side particularly, as the gate weight will accelerate the lean

Costs of Small Repairs vs. Letting Things Go

Replacing a single rotted gravel board typically costs in the region of £20-£40 for the board plus a call-out visit. Leaving it until the panel base has rotted through means replacing the panel as well, adding £80-£150 to the cost. Fixing one loose arris rail costs a small amount of time and fixing. Letting it fail means a section of boards comes down, often taking adjacent boards or panels with it in the next storm.

Preventive maintenance costs very little. If you want to call us for a look at your fence after a repair, or to check a run that has not been touched in several years, call us and we can give you an honest view of what - if anything - needs attention.
